Abstract
We report on the continuous-wave and passively Q-switched waveguide laser at the wavelength of ∼1024 nm, based on the (Yb0.1Y0.9)3(Sc1.5Ga0.5)Ga3O12 (Yb:YSGG) crystal. The ridged waveguide was fabricated on the surface of 100 at% Yb:YSGG crystal by the swift ion irradiation and the precise diamond blade dicing. Utilizing this waveguide as the gain medium and resonant cavity, the laser emission at ∼1024 nm was realized. Coating the tungsten disulfide onto the waveguide surface as the saturable absorber, the Q-switched laser emission was also obtained with the pulse duration of 125 ns.
